The Remote Control Panel Indicator (RCPI) is designed to be powered by a single Duracell PX28L 6 volt lithium battery, or equivalent. Alkaline batteries, such as Eveready A 544, or equivalent may also be used. Under normal operating conditions, the lithium battery must be replaced every 10 years. The alkaline batteries must be replaced every 5 years. If the ELT is activated for an unknown period of time, the battery must be replaced. For additional information see the ACK Technologies Inc. Model E-04 ELT Installation/Operation Manual, Section 4.
Note: 
The Audio Annunciator Battery should be checked and replaced at the same time. (ELT Audio Alert Indicator Battery Replacement)
Task Instructions
1. Remove the overhead console bezel and overhead console mount. (Overhead Console Component Replacement)
2. Locate the ELT RCPI.
3. Use a T10 Torx driver to remove the four 6-32 screws attaching the black ICA009273 bracket to the RCPI and orange audio alert indicator, then remove the bracket and remove the RCPI.
4. Remove the three 6-32 retaining screws which secure the top and bottom half of the RCPI unit.
5. Carefully remove the top half of the RCPI, exposing the battery compartment.
6. Carefully inspect the battery contacts for dirt or corrosion. If the contacts need cleaning, use only non-abrasive electrical contact cleaner and a stiff brush. Abrasive cleaners will remove the nickel and gold plating from contacts.
7. Insert the battery with the polarity matching the engraving on the bottom of the battery compartment.
8. Join the halves of the RCPI case together and tighten the three remaining screws.
9. Mount the RCPI and audio alert indicator back into the overhead console, securing them with the ICA009273 bracket and four screws.
10. Replace the overhead console mount.
11. Replace the overhead console bezel.
12. The next RCPI battery replacement date should be recorded in the aircraft logbook with a note indicating the battery expiration dates.
Verification Method
After battery replacement, perform the ELT battery self test per ELT Battery Self Test.
